From Classrooms to Championships

Programming teachers, vocational schools, and international coding competitions rely on NStrim to eliminate setup time and get students coding from minute one.

One platform, three ways to use it

Whether it's a Tuesday afternoon class or a European championship, the workflow is the same.

Everyday Classroom

Class starts. Students code.

The challenge

Every class starts the same way: 30 minutes lost to broken installs, wrong PHP versions, and the dreaded "it works on my machine." By the time everyone has a running environment, half the lesson is gone.

With NStrim

The teacher creates a session and shares an access code. Students enter it and instantly have their own server, database, and live URL — ready for any framework. No installs. No configuration. Class starts, students code.

30 min saved per class on environment setup
"My XAMPP won't start"
"I have PHP 7.4, not 8.2"
"MySQL isn't connecting"
"Everyone is coding. First minute."
Competition Day

Fair play at any scale.

The challenge

Running a programming championship means manually configuring 20+ identical machines, praying nothing crashes mid-competition, and fielding complaints that one competitor's environment was different from another's.

With NStrim

Every competitor gets an identical, isolated environment provisioned automatically. Organizers control timers, push task amendments, and monitor live sites from one dashboard. Judges grade from a dedicated marking room with full access to code and live deployments.

All environments identical. All timers synced.

Timed Exam

Exams you can actually trust.

The challenge

Coding exams without isolation are a liability. Students share servers, peek at each other's work, or claim technical problems ate their submission. No reliable way to prove who wrote what.

With NStrim

Each student gets a completely isolated environment with a countdown timer that auto-locks when time expires. Every commit is timestamped. The teacher reviews all submissions from a grading dashboard. No shared environments, no ambiguity.

What educators say

JK
Janis K.
Programming Teacher, Technical Secondary School
"I used to dread the first 30 minutes of every lesson. Now my students push their first commit before I finish explaining the task."
ML
Marta L.
Chief Expert, National Skills Organization
"We ran a championship for 24 competitors across three frameworks. Every environment was identical, every timer synced to the second. Zero complaints."
EV
Elena V.
CS Department Lead, University of Applied Sciences
"For the first time, I could hand out grades without a single student contesting the conditions. Everyone had the same setup, the same clock, the same rules."
TN
Tomas N.
IT Administrator, Vocational School
"No more VMs to configure, no more student machines to troubleshoot. NStrim took server management off my plate completely."
AS
Anna S.
Lead Instructor, Coding Bootcamp
"Our students come from completely different backgrounds. Some have never used a terminal. With NStrim, that doesn't matter — they just code."

5 years. 6 countries. One platform.
